New computer - Move subscription

I have 100 day or so left on my Norton subscription. I have bought a new laptop and would like to transfer the account to it.  What all ways impressed me with Norton's was I never had to worry about moving from one PC to the other. I just had to remember my login and BAM I was on my way!! 

 

How dose one do that on win7 with a per-installed Norton's

 

Thanks
